Enterprise Networking & Security
VPN design should make remote work, branch connectivity, and partner access safer and easier to support. Sun Life Tech helps businesses plan, clean up, migrate, and troubleshoot VPN environments without relying on guesswork.

Quick navigation
Use the jump links below to move through planning, design, security, vendor support, and next-step topics.
We can review the current environment, the risk, and the operational impact before you commit to a migration, firewall replacement, or managed support plan.
Security delivery
This support sits inside the same documented risk, access, supplier, and continuity framework used across Sun Life Tech services.
Sun Life Tech self-declares conformity of its Information Security Management System with ISO/IEC 27001:2022 within its defined scope. Our ISMS addresses risk management, controlled access, supplier oversight, incident response, continuity planning, internal review, and continual improvement.
First-party declaration; not accredited third-party certification.
The business problem may be remote work, branch connectivity, vendor access, or a phased migration. Those scenarios do not all need the same design.
Secure access for staff, leadership, and contractors working from home or traveling.
Branch offices, plants, clinics, and partner locations that need stable private connectivity.
Balance user experience, MFA, and route selection when staff split time between office and remote work.
Provide controlled access paths without turning every third party into a trusted insider.
A VPN can be technically functional and still operationally poor if identity, routing, and endpoint expectations are not clear.
User issues may be tied to DNS, MFA, split tunneling, local ISP behavior, certificate state, or resource-side access controls. A supportable design makes those issues easier to isolate.
Identify which users, sites, vendors, or applications actually need private connectivity.
Define the authentication path, routes, DNS behavior, and what resources the tunnel should expose.
Test user workflows and record the settings, dependencies, and support notes.
Review tunnel health, certificate dates, client behavior, and changes in business access needs.
